What is CPU? what is it use for?
IT is central processing unit
All kinds of computing devices such as tablets, PCs, or laptops feature a brain-like unit called the central processing unit or CPU. Your computer’s CPU calculates and interprets instructions while you’re surfing the web, creating documents, playing games, or running software programs.
What is RAM and what is use for?
Random Access Memory
RAM is a temporary memory bank where your computer stores data it needs to retrieve quickly. RAM keeps data easily accessible so your processor can quickly find it without having to go into long-term storage to complete immediate processing tasks.Sept 9, 2022
What is SDRAM? what is it use for?
Synchronous Dynamic RAM
DDR, DDR2, DDR3, DDR4 – Double Data Rate SDRAM
SDRAM (synchronous DRAM) is a generic name for various kinds of dynamic random access memory (DRAM) that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time.
What is ROM? what is it use for?
Read Only Memory
ROM (read-only memory) is a non-volatile memory type. This means it receives data and permanently writes it on a chip, and it lasts even after you turn off your computer. The data is coded to not be overwritten, so it’s used for things like your printer software or your startup programs.Mar 1, 2021
What is bios? what is it use for?
BASIC INPUT OUTPUT SYSTEM
is the program a computer’s microprocessor uses to start the computer system after it is powered on. It also manages data flow between the computer’s operating system (OS) and attached devices, such as the hard disk, video adapter, keyboard, mouse and printer.
What is PCI? what is it use for?
Peripheral component interconnect
Obsolete, replaced with PCO express (PCIe)
Percutaneous coronary intervention (PCI) refers to a family of minimally invasive procedures used to open clogged coronary arteries (those that deliver blood to the heart). By restoring blood flow, the treatment can improve symptoms of blocked arteries, such as chest pain or shortness of breath.
what is Data flow and how does it work
Data flow is the path the system’s information takes from external entities through processes and data stores. With arrows and succinct labels, the DFD can show you the direction of the data flow. Before you start mapping out data flow diagrams you need to follow four best practices to create a valid DFD.May 13, 2021
